Key Takeaways

  • Dry eyes happen when your eyes don’t make enough tears, or when your tears lack the quality needed to keep your eyes comfortable.
  • Medications, hormone changes, health conditions, blocked eyelid oil glands, eye surgery, and age can all play a role.
  • Simple home steps, like warm compresses and a humidifier, can help ease mild symptoms.
  • An optometrist can find out what’s behind your dry eyes and recommend management options like OptiLight.

Dry Eye Can Have a Number of Causes

You wake up and your eyes feel gritty, like sand slipped under your lids overnight. By afternoon, the spreadsheet on your screen starts to look blurry, and you find that you’re blinking more than usual. As optometrists in Boise, our team at Vision One Boise often hears from adults experiencing sudden dry eye symptoms.

Dry eyes can appear suddenly because of a new medication, a hormone change, a health condition, blocked oil glands in your eyelids, recent eye surgery, or getting older. Finding the cause is the first step towards relief, so a visit with our dry eye care team can help you pinpoint what’s going on.

What Are Dry Eyes?

Dry eyes happen when your eyes don’t make enough tears or when your tears lack the quality to keep your eyes comfortable.

Your tears have 3 layers: mucus, water, and oil. A problem with any one of these or with your tear production in general can leave your eyes feeling itchy and dry.

Signs & Symptoms of Dry Eyes

Dry eyes can show up in ways that you might not expect. Common signs include:

  • Your eyes feel burning, itchy, or scratchy.
  • Your eyes look red.
  • Your vision turns blurry.
  • Bright light feels uncomfortable.
  • Your eyes water.
  • Stringy mucus collects around your eyes.

Conditions with Similar Signs

Some of these symptoms of dry eye overlap with the symptoms of other eye problems. Conditions with similar signs include:

  • Allergies, which can cause itchy, irritated eyes.
  • Eye infections, which may bring thicker or darker mucus.
  • Watery eyes, which may point to a condition called ocular rosacea.

An eye exam can help sort out which condition you’re actually dealing with.

Common Causes of Dry Eyes

Sudden dryness often traces back to changes in your health or routine.

Medications & Allergies

Oral antihistamines for allergies can also lower your tear supply. Your risk of dry eye may also increase when you take several medications or supplements at once.

Hormone Changes & Health Conditions

Shifts in your hormones can also affect your eyes. Pregnancy, menopause, birth control, and hormone medications have all been linked to dry eyes.

Health conditions such as Sjögren’s syndrome, lupus, rheumatoid arthritis, thyroid problems, and other autoimmune conditions can play a role as well.

Eyelid Oil Glands, Eye Surgery, & Age

Small glands on the edges of your eyelids produce the oils that help your tears lubricate your eyes. If these glands become blocked or swollen, this can leave your eyes feeling dry.

Dryness is also common after LASIK, in which case it often eases within 12 months. Age matters too, since your eyes make fewer tears as you get older.
